Q1. What's is difference between classless and classful network?

Ans.

Classful networks use fixed-length subnet masks, while classless networks use variable-length subnet masks.

Classful networks divide IP addresses into predefined classes (A, B, C, etc.)
Classful networks have fixed subnet masks based on the class of the network.
Classless networks use variable-length subnet masks (VLSM) to divide IP addresses into subnets of different sizes.
Classless networks allow for more efficient use of IP addresses and better network scalability.
Example: Cl...read more

Ans.

Hard disk is a permanent storage device, while RAM is a temporary storage device.

Hard disk is used for long-term storage of data, while RAM is used for short-term storage of data that is actively being used by the computer.
Hard disk is non-volatile, meaning the data remains even when the computer is turned off, while RAM is volatile and loses its data when the computer is powered off.
Hard disk has larger storage capacity compared to RAM. For example, a typical hard disk can s...read more

IPv4 uses decimal notation (e.g., 192.168.0.1), while IPv6 uses hexadecimal notation (e.g., 2001:0db8:85a3:0000:0000:8a2e:037...read more

Are these interview questions helpful?

Ans.

Subnetting is the process of dividing a network into smaller subnetworks to improve network efficiency and security.

Subnetting allows for better utilization of IP addresses by dividing a network into smaller subnets.
It helps in improving network performance by reducing network congestion.
Subnetting enhances network security by isolating different departments or groups within an organization.
Subnetting is achieved by using subnet masks to determine the network and host portion...read more
